Cardiosense Announces Publication of SEISMIC-HF I Study Results in the Journal of the American College of Cardiology: Heart Failure
The prospective, multi-center SEISMIC-HF I study enabled the development and evaluation of Cardiosense's ML algorithm in 310 patients with HFrEF undergoing right heart catheterization (RHC). The study population enrolled a diverse set of participants with demographics and clinical characteristics reflective of the broader population with HFrEF to ensure ML models generalize across all patients. Patients enrolled in the study wore the CardioTag device–a multi-modal sensor that captures seismocardiogram (SCG), electrocardiogram (ECG), and photoplethysmogram (PPG) signals–on their sternum during the RHC procedure used to provide gold standard assessment of an individual's PCWP.
Key findings from the 15-site study show that the device:
Estimated absolute PCWP values with accuracy on par with implantable hemodynamic sensors, suggesting that Cardiosense's noninvasive, AI-enabled technology has the potential to increase access to hemodynamic-guided care.
Demonstrated a consistent performance across sex, race, ethnicity, and body mass index.
Additional analysis available in the full manuscript, titled 'Noninvasive Pulmonary Capillary Wedge Pressure Estimation in Heart Failure Patients With the Use of Wearable Sensing and AI,' available now in JACC: Heart F ailure.
"Heart failure management remains one of our most significant clinical challenges and most promising opportunities to directly impact patient outcomes," said Liviu Klein, MD, MS, Section Chief of Advanced Heart Failure, Mechanical Circulatory Support, Pulmonary Hypertension, and Heart Transplant at UCSF, lead author on the study and lead clinical advisor for Cardiosense. "We know that hemodynamic-guided care reduces hospital readmissions and mortality, yet routine cardiac pressure measurements remain inaccessible due to cost and risk. SEISMIC-HF I is a critical advancement toward the quest for noninvasive technology delivering on the promise of fast, safe, and accessible pressure-guided heart failure management.'
Initial results from Cardiosense's SEISMIC-HF I study were presented as Late-Breaking Science at the American Heart Association's 2024 Scientific Sessions.
'This analysis marks a real milestone in our journey to revolutionize heart failure management with our proprietary AI technology that leverages noninvasive sensor data to deliver critical information on cardiac function,' said Omer Inan, PhD, Cardiosense Co-founder and Chief Scientific Officer. 'The results are a culmination of more than a decade of research and a testament to the cross-disciplinary collaboration from our team of medical and clinical experts, data scientists, and engineers.'

CHAMPgov Selected by Louisiana to Digitally Transform the State's OMV
CLEVELAND--(BUSINESS WIRE)--CHAMP Titles, Inc. ('CHAMP'), the nation's leading provider of digital title and registration and e-lien programs, as well as vehicle and driver services systems of record, today announced the signing of a contract with the state of Louisiana to implement and launch the CHAMPgov platform, bringing cutting-edge digital transformation to its Office of Motor Vehicles. CHAMP, the nation's leading provider of digital title, registration, e-lien, and driver services systems, has been selected by Louisiana to launch the CHAMPgov platform. The initiative will bring cutting-edge digital transformation to the state's OMV. Louisiana will be implementing both CHAMP's Vehicle Services and Driver Services platforms, replacing outdated systems and paper-based processes with fully digital, cloud-native solutions that will deliver benefits to the state agency, the citizens of Louisiana, and all industry stakeholders. 'Louisiana is blazing a trail for digital government,' said Shane Bigelow, CEO of CHAMP. 'By leveraging our core platforms, the state is not only modernizing its own system but setting a national standard for innovation in public service. This milestone marks the continued rapid expansion of CHAMP across the country and brings us one step closer to a fully digital future for state government. We are honored and proud to partner with Governor Landry, Commissioner Adams, and all the amazing Louisianans on this effort and to serve the amazing citizens of Louisiana.' With Louisiana's adoption of both CHAMP's Vehicle and Driver Services platforms, more than 35 million Americans will benefit from CHAMP's modern government infrastructure. It enables streamlined title, lien, registration, and driver credential processing, along with full visibility into the vehicle lifecycle.
